lClaim.

This invention has been developed with' particular reference to its usein connection with meters for gasoline and other iluids and will bedescribed with reference to such use but as this 5 description proceedsit will be seen that it Vis capable of application to other uses. In themovement or sale of various commodities, such as gasoline. for example,in connection with which registration is effected of the quantity of thecommodity or the price it is often necessary to provide means foreffecting compensation, as for a change in unit price or for a change oftemperature, or'for some-other reason, between the measuringinstrumentality, such as a meter, and

the register mechanism. To meet the demand for such provision it hasbeen the practice for many years of manufacturers of water meters,gasoline meters, etc., to deliver with every meter and its registermechanism several pair of single change gears, of different ratios, toreplace, as conditions may require, the 4gears removably mounted on thedriving shaft and the driven shaft through which the register mechanismis actuated from the meter, such single change gears being properlymarked according to the result to be produced. The substitution of suchchange gears necessitates the dismemberment of the apparatus to alimited extent and requires the services of a competent mechanic. It hasbeen the object of the present invention to provide a construction whichcan be built into the apparatus and by which compensation of theregister mech-v anism can be effected readily to accommodate changedconditions of operation. In accordance with the invention several pairsof differential gears are mounted upon a movable carrier so thatA a pairnecessary to compensate for a change in operating conditions, such as achange in unit price, may be brought into operative relation with thegear actuated by the meter and the driving gear of the registermechanism.

The invention will be more fully explained hereinafterl with referenceto the accompanying drawings in which it is illustrated, and in which:Figure 1 is a view in sectional elevation of a meter in which theimproved compensating device is incorporated between the metermechanism, a portion of the casing of which is shown, and the registermechanism which is shown main- 5 catedlb'y the hrgkenune'afa of Figure2.

ly in outline, the compensating mechanism beingv (Cl. 'I4-58) Figure 4is a view in side elevation of the compensating mechanism. l

Figure 5 is a detail view in section, on a larger scale, through one ofthe pairs of dierential gears and the gears. with which they coact. 30

Figure 6 is a detail view, on a larger scale, of the drivingconnectionbetween the compensating mechanism and the register mechanism.

The measuring instrumentality, as indicated at A, may be of any usual orsuitable construction, having, in the form illustrated, a pinion a inengagement-with a gear b of the compensaty ing mechanism which is showngenerally at'B. The register mechanism may also be of any usual orsuitable construction and is therefore shown in outline only. It is hereshown` as arranged at an angle with respect to the compensating'mechanism and the top of the meter and may be driven from thecompensating mechanism through gearing to be described.

The compensating mechanism is mounted to rotate on asupporting plate b1and comprises a cylindrical rotatable carrier formed of two annularplates b2 and b3 and an enclosing wall b4. The plate b3 is shown asformed with gear 80 teeth, as at b, for engagement with a pinion b5mounted on a stud b8 secured to the plate b1 and provided with two pinsb" for engagement by a detent ba carried by a. door b9 of the housing cof the register mechanism. When the door 'is closed and locked, asordinarily, accidental movement or improper manipulation of thecompensating mechanism is thus prevented. In the plates I)2 and ba aremounted pins b1. on each of which are mounted two diierential gears b,bm connected to rotate together with a. sleeve bn. The two gears of eachpair have diierent numbers o-f teeth and the corresponding gears of theseveral pairs have diierent numbers of teeth. Thus, the lower gearbll'of each pair may 95 have 28 teeth, while the upper gear of. the samepair may have 27 teeth; the gears of the second f pair may have 29 teethand 28 teeth respective-` ly; the gears of the third pair may have 30teeth ,and 29 teeth respectively; and so on. 100

Mounted in a suitable bearing supported byr the plate b1 eccentricallywith respect to the annular plates b2, l)3 is a spindle b14 which hassecured to ita diiferential gear Z115 and receives above the gearb15 agear b1 carried by a sleeve 105 b1" mounted loosely on the spindle. Atits upper end the sleeve b1" carries a driving head bla which, ln theconstruction illustrated, is provided with pins b1 adapted to engage askew gear b2 rotambl'y supported by the bottom plate c1 or the 110 rilhousing c of the register mechanism and engaging a coacting skew gearb21 on the drive shaft i322 of the register mechanism. The two gearsi915 and o16 are also differential gears, the one having, it may be, 30teeth while the other has, it may he, 31 teeth.

lThe teeth of the gears 2211 and b of the several pairs oi differentialgears, mounted on the rotatable carrier, and the teeth of the gears E15and i116, mounted on the eccentrically disposed spindle i914, are out sothat any of the upper gears "cl2 will run smoothly with the gear Z315While amT o the gears i311 will run smoothly with. the gear 1715. ln theembodiment oi the invention illustrated when the gears of the fourthpair, having respectively 3l teeth and 30 teeth, are in mesh with thegears i115 and Z915, the spindle D14 and the driving head b1 turn at thesame speed, the gear ratio oei-ng 2.909. if then the gear frame orcarrier is turned so as to bring gears of the third pair, havingrespectively 3 teeth and 29 teeth into mesh. with the gears '015 and"o16 the .9989, or a difieren-e of alzaout onev'tentli of one uercentlIn pair or" diereatial a diffe H oe established between the spindle andthe driv ing head and the measuring therefore between 'rumentality orineter and the register inechaill be understood that within the limitsden 'terriined hy the 1 tios oi the several sets rential gears supportedhy the rotatable carany desired ratio between the measuringinstrumentality the register mechanism can ist established by .ening theT39 oi the regter mechanism, there i' unlocking the comn pensatingmechanism, and then rotating the carrier to bring into mesh with thegears on the spindle b14 the proper pair of differential gears i111,i312, as indicated by suitable marking on the circumferential wall b4 ofthe carrier brought into alignment with the pointer 1123.

The enclosing Wall b4 has formed thereon figures or characters, as shownin Figure 4, which represent the setting of the compensating mechanism,and in order that a visual indication of the setting may be had at alltimes from the outside a window is provided at a suitable point in thecasing, as at o in the door b9, through which the gures on thecompensating mechanisrn may be read.

It will oe understood that various changes in arrangement and relationof parts can be made to suit different conditions of use and that, except as pointed .out the accompanying claim, the invention is notrestricted to the particular construction shown and described herein. Itwill also ne understood that the compensating mechanism is capable ofuse in connection. with other measuring instrumentalities and otherforms of registers than those illustrated.

l claim as my invention:

A compensating mechanism comprising two gears mounted to rotateindependently on a coininon airis, a movable gear carrier, a series ofpairs oi diierential gears supported by said carrier, gears of each pairbeing adapted to rotate together and to engage respectively the nrstnained gears, a housing, a door for said housing, and means carried bysaid door and adapted when the door is closed to engage operatively thecarrier 'to prevent movement thereof.
